EXAMPLES Example 1 Safety and Efficacy of Ultra-Pure EPA

A multi-center, placebo-controlled, randomized, double-blind, 12-weekstudy is performed to evaluate the efficacy and safety of >96% E-EPA inpatients with fasting triglyceride levels ≥200 mg/dl and <500 mg/dldespite statin therapy (the mean of two qualifying entry values needs tobe ≥185 mg/dl and at least one of the values needs to be ≥200 mg/dl).The primary objective of the study is to determine the efficacy of >96%E-EPA 2 g daily and 4 g daily, compared to placebo, in lowering fastingTG levels in patients with high risk for cardiovascular disease and withfasting TG levels ≥200 mg/dL and <500 mg/dL, despite treatment to LDL-Cgoal on statin therapy.

The secondary objectives of this study are the following:

-   1. To determine the safety and tolerability of >96% E-EPA 2 g daily    and 4 g daily;-   2. To determine the effect of >96% E-EPA on lipid and apolipoprotein    profiles including total cholesterol (TC), non-high-density    lipoprotein cholesterol (non-HDL-C), low density lipoprotein    cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C),    and very high density lipoprotein cholesterol (VHDL-C);-   3. To determine the effect of >96% E-EPA (on lipoprotein associated    phospholipase A₂ (Lp-PLA₂) from baseline to week 12;-   4. To determine the effect of >96% E-EPA on low-density lipoprotein    (LDL) particle number and size;-   5. To determine the effect of >96% E-EPA on oxidized LDL;-   6. To determine the effect of >96% E-EPA on fasting plasma glucose    (FPG) and hemoglobin A_(1c) (HbA_(1c));-   7. To determine the effect of >96% E-EPA on insulin resistance;-   8. To determine the effect of >96% E-EPA on high-sensitivity    C-reactive protein (hsCRP);-   9. To determine the effects of >96% E-EPA 2 g daily and 4 g daily on    the incorporation of fatty acids into red blood cell membranes and    into plasma phospholipids;-   10. To explore the relationship between baseline fasting TG levels    and the reduction in fasting TG levels; and-   11. To explore the relationship between changes of fatty acid    concentrations in plasma and red blood cell membranes, and the    reduction in fasting TG levels.

The population for this study is men and women >18 years of age with abody mass index ≤45 kg/m² with fasting TG levels greater than or equalto 200 mg/dl and less than 500 mg/dl and on a stable does of statintherapy (with or without ezetimibe). The statin must be atorvostatin,rosuvastatin or simvastatin. The dose of statin must be stable for ≥4weeks prior to the LDL-C/TG baseline qualifying measurement forrandomization. The statin dose will be optimal such that the patientsare at their LDL-C goal at the LDL-C/TG baseline qualifyingmeasurements. The same statin at the same dose will be continued untilthe study ends.

Patients taking any additional non-statin, lipid-altering medications(niacin >200 mg/day, fibrates, fish oil, other products containingomega-3 fatty acids, or other herbal products or dietary supplementswith potential lipid-altering effects), either alone or in combinationwith statin therapy (with or without ezetimibe), must be able to safelydiscontinue non-statin, lipid-altering therapy at screening.

Patients at high risk for CVD, i.e., patients with clinical coronaryheart disease (CHD) or clinical CHD risk equivalents (10-year risk >20%)as defined in the National Cholesterol Education Program (NCEP) AdultTreatment Panel III (ATP III) Guidelines will be eligible to participatein this study. Those include patients with any of the followingcriteria: (1) Known CVD, either clinical coronary heart disease (CHD),symptomatic carotid artery disease (CAD), peripheral artery disease(PAD) or abdominal aortic aneurism; or (2) Diabetes Mellitus (Type 1 or2).

Approximately 648 patients will be randomized at approximately 80centers in the U.S. The study will be a 18- to 20-week, Phase 3,multi-center study consisting of 2 study periods: (1) A 6- to 8-weekscreening period that includes a diet and lifestyle stabilization, anon-statin lipid-altering treatment washout, and an LDL-C and TGqualifying period and (2) A 12-week, double-blind, randomized,placebo-controlled treatment period.

During the screening period and double-blind treatment period, allvisits are to be within ±3 days of the scheduled time. All patients willcontinue to take the statin product (with or without ezetimibe) at thesame dose they were taking at screening throughout their participationin the study.

The 6- to 8-week screening period includes a diet and lifestylestabilization, a non-statin lipid-altering treatment washout, and anLDL-C and TG qualifying period. The screening visit (Visit 1) will occurfor all patients at either 6 weeks (for patients on stable statintherapy [(with or without ezetimibe] at screening) or 8 weeks (forpatients who will require washout of their current non-statinlipid-altering therapy at screening) before randomization, as follows:

-   Patients who do not require a washout: The screening visit will    occur at Visit 1 (Week-6). Eligible patients will enter a 4-week    diet and lifestyle stabilization period. At the screening visit, all    patients will receive counseling regarding the importance of the    National Cholesterol Education Program (NCEP) Therapeutic Lifestyle    Changes (TLC) diet and will receive basic instructions on how to    follow this diet.-   Patients who will require a washout: The screening visit will occur    at Visit 1 (Week-8). Eligible patients will begin a 6-week washout    period at the screening visit (i.e. 6 weeks washout before the first    LDL-C/TG qualifying visit). Patients will receive counseling    regarding the NCEP TLC diet and will receive basic instructions on    how to follow this diet. Site personnel will contact patients who do    not qualify for participation based on screening laboratory test    results to instruct them to resume their prior lipid-altering    medications.

At the end of the 4-week diet and lifestyle stabilization period or the6-week diet and stabilization and washout period, eligible patients willenter the 2-week LDL-C and TG qualifying period and will have theirfasting LDL-C and TG levels measured at Visit 2 (Week-2) and Visit 3(Week-1). Eligible patients must have an average fasting LDL-C level ≥40mg/dL and <100 mg/dL and an average fasting TG level ≥200 mg/dL and <500mg/dL to enter the 12-week double-blind treatment period. The LDL-C andTG levels for qualification will be based on the average (arithmeticmean) of the Visit 2 (Week-2) and Visit 3 (Week-1) values. If apatient's average LDL-C and/or TG levels from Visit 2 and Visit 3 falloutside the required range for entry into the study, an additionalfasting lipid profile can be collected 1 week later at Visit 3.1. If athird sample is collected at Visit 3.1, entry into the study will bebased on the average (arithmetic mean) of the values from Visit 3 andVisit 3.1.

After confirmation of qualifying fasting LDL-C and TG values, eligiblepatients will enter a 12-week, randomized, double-blind treatmentperiod. At Visit 4 (Week 0), patients will be randomly assigned to 1 ofthe following treatment groups:

-   >96% E-EPA 2 g daily,-   >96% E-EPA 4 g daily, or-   Placebo.

Approximately 216 patients per treatment group will be randomized inthis study. Stratification will be by type of statin (atorvastatin,rosuvastatin or simvastatin), the presence of diabetes, and gender.

During the double-blind treatment period, patients will return to thesite at Visit 5 (Week 4), Visit 6 (Week 11), and Visit 7 (Week 12) forefficacy and safety evaluations.

Eligible patients will be randomly assigned at Visit 4 (Week 0) toreceive orally >96% E-EPA 2 g daily, >96% E-EPA 4 g daily, or placebo.

>96% E-EPA is provided in 1 g liquid-filled, oblong, gelatin capsules.The matching placebo capsule is filled with light liquid paraffin andcontains 0 g of >96% E-EPA. >96% E-EPA capsules are to be taken withfood (i.e. with or at the end of a meal).

During the double-blind treatment period, patients will take 2 capsules(>96% E-EPA or matching placebo) in the morning and 2 capsules in theevening for a total of 4 capsules per day.

-   Patients in the >96% E-EPA 2 g/day treatment group will receive    1>96% E-EPA 1 g capsule and 1 matching placebo capsule in the    morning and in the evening.-   Patients in the >96% E-EPA 4 g/day treatment group will receive    2>96% E-EPA 1 g capsules in the morning and evening.

Patients in the placebo group will receive 2 matching placebo capsulesin the morning and evening.

The primary efficacy variable for the double-blind treatment period ispercent change in TG from baseline to Week 12 endpoint. The secondaryefficacy variables for the double-blind treatment period include thefollowing:

-   Percent changes in total cholesterol (TC), high-density lipoprotein    cholesterol (HDL-C), LDL-C, calculated non-HDL-C, and very    low-density lipoprotein cholesterol (VLDL-C) from baseline to Week    12 endpoint;-   Percent change in very low-density lipoprotein TG from baseline to    Week 12;-   Percent changes in apolipoprotein A-I (apo A-I), apolipoprotein B    (apo B), and apo A-I/apo B ratio from baseline to Week 12;-   Percent changes in lipoprotein(a) from baseline to Week 12;-   Percent changes in LDL particle number and size, measured by nuclear    magnetic resonance, from baseline to Week 12;-   Percent change in remnant-like particle cholesterol from baseline to    Week 12;-   Percent change in oxidized LDL from baseline to Week 12;-   Changes in FPG and HbA_(1c) from baseline to Week 12;-   Change in insulin resistance, as assessed by the homeostasis model    index insulin resistance, from baseline to Week 12;-   Percent change in lipoprotein associated phospholipase A₂ (Lp-PLA₂)    from baseline to Week 12;-   Change in intracellular adhesion molecule-1 from baseline to Week    12;-   Change in interleukin-2 from baseline to Week 12;-   Change in plasminogen activator inhibitor-1 from baseline to    Week 12. Note: this parameter will only be collected at sites with    proper storage conditions;-   Change in hsCRP from baseline to Week 12; and-   Change in plasma concentration and red blood cell membrane content    of fatty acid from baseline to Week 12 including EPA,    docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), arachidonic    acid (AA), dihomo-γ-linolenic acid (DGLA), the ratio of EPA/AA,    ratio of oleic acid/stearic acid (OA/SA), and the ratio of total    omega-3 acids over total omega-6 acids.

Safety assessments will include adverse events, clinical laboratorymeasurements (chemistry, hematology, and urinalysis), 12-leadelectrocardiograms (ECGs), vital signs, and physical examinations.

For TG, TC, HDL-C, LDL-C, calculated non-HDL-C, and VLDL-C, baselinewill be defined as the average of Visit 4 (Week 0) and the precedinglipid qualifying visit (either Visit 3 [Week-1] or if it occurs, Visit3.1) measurements. Baseline for all other efficacy parameters will bethe Visit 4 (Week 0) measurement.

For TG, TC, HDL-C, LDL-C, calculated non-HDL-C, and VLDL-C, Week 12endpoint will be defined as the average of Visit 6 (Week 11) and Visit 7(Week 12) measurements.

Week 12 endpoint for all other efficacy parameters will be the Visit 7(Week 12) measurement.

The primary efficacy analysis will be performed using a 2-way analysisof covariance (ANCOVA) model with treatment as a factor and baseline TGvalue as a covariate. The least-squares mean, standard error, and2-tailed 95% confidence interval for each treatment group and for eachcomparison will be estimated. The same 2-way ANCOVA model will be usedfor the analysis of secondary efficacy variables.

The primary analysis will be repeated for the per-protocol population toconfirm the robustness of the results for the intent-to-treatpopulation.

Non-inferiority tests for percent change from baseline in LDL-C will beperformed between >96% E-EPA doses and placebo using a non-inferioritymargin of 6% and a significant level at 0.05.

For the following key secondary efficacy parameters, treatment groupswill be compared using Dunnett's test to control the Type 1 error rate:TC, LDL-C, HDL-C, non-HDL-C, VLDL-C, Lp-PLA₂, and apo B. For theremaining secondary efficacy parameters, Dunnett's test will not be usedand the ANCOVA output will be considered descriptive.

The evaluation of safety will be based primarily on the frequency ofadverse events, clinical laboratory assessments, vital signs, and12-lead ECGs. The primary efficacy variable is the percent change infasting TG levels from baseline to Week 12. A sample size of 194completed patients per treatment group will provide 90.6% power todetect a difference of 15% between >96% E-EPA and placebo in percentchange from baseline in fasting TG levels, assuming a standard deviationof 45% in TG measurements and a significance level of p<0.05.

Previous data on fasting LDL-C show a difference in percent change frombaseline of 2.2%, with a standard deviation of 15%, between study drugand placebo. A sample size of 194 completed patients per treatment groupwill provide 80% power to demonstrate non-inferiority (p<0.05,one-sided) of the LDL-C response between >96% E-EPA 4 g daily andplacebo, within a 6% margin. To accommodate a 10% drop-out rate fromrandomization to completion of the double-blind treatment period, atotal of 648 randomized patients is planned (216 patients per treatmentgroup).

Example 2 Improvement of Cognitive Performance in Subjects WithAge-Associated Memory Impairment

A single-center, 6-week, double-blind, randomizes, parallel-group,placebo-controlled, dose-ranging pilot study was performed to evaluatethe efficacy, tolerability, and safety of >96% ethyl-EPA in subjectswith subjective and objective memory impairment according to generallyaccepted criteria for Age-Associated Memory Impairment (“AAMI”). Theprimary objective of the study was to determine the effect of >96%ethyl-EPA 1 g, 2 g, and 4 g daily, compared to placebo, on cognitiveperformance in subjects with AAMI.

The secondary objectives of this study were the following:

-   1. To determine the effect of >96% E-EPA on the following tests in    the computerized cognitive battery:    -   Continuity of attention tasks;    -   Quality of working memory tasks;    -   Quality of episodic memory tasks; and    -   Speed of attention tasks;-   2. To determine the safety and tolerability of >96% E-EPA from    routine clinical laboratory tests, adverse events (“AE”) monitoring,    and vital signs; and-   3. To determine the potential dose-effect relationship of >96% E-EPA    on the cognitive endpoints by measurement of essential fatty acids    in plasma and red blood cell membranes.

The population for this study was men and women between ages 50 and 70with self-reported complaints of memory loss, subjective and objectivecognitive impairment with a score of at least one standard deviationbelow that of the mean for age-matched elderly population as determinedby the total score of between 13 and 20 from the Paired AssociatedLearning (“PAL”) subset of the Wechsler Memory Scale, evidence ofadequate intellectual function as determined by a scaled score of atleast 9 (raw score of at least 32) on the Vocabulary subtest of theWechsler Adult Intelligence Scale and absence of dementia as determinedby a score of 24 or higher on the Mini-Mental State Examination(“MMSE”).

Potential subjects were excluded based on the following exclusioncriteria:

-   Unlikely or unable to comply with investigational medication dosing    requirements;-   Diagnosis of major depressive disorder, Alzheimer's or vascular    dementia as defined according to the Mini International    Neuropsychiatric Interview (“MINI”)/Diagnostic and Statistical    Manual of Mental Disorders (4th edition) Text Revision (“TR”)    criteria;-   Past or current history of:    -   a neurological or psychiatric disorder that could have affected        cognitive function;    -   inflammatory gastrointestinal disease such as Crohn's Disease or        ulcerative colitis;    -   cancer other than basal cell carcinoma;    -   clinically significant cardiac abnormality as measured by        12-lead ECG;-   Any other medical condition or intercurrent illness not adequately    controlled, which, in the opinion of the study investigator, may    have put the subject at risk when participating in the study or may    have influenced the results of the study or affected the subject's    ability to take part in the study;-   Clinically significant abnormal screening results (e.g.,    haematology, biochemistry) on screening or vital signs that fell    outside the normal range for this population, which in the opinion    of the study investigator affected the subject's suitability for the    study;-   Changes to prescribed medication for a medical condition within 4    weeks of the baseline visit;-   Omega-3 supplementation within 4 weeks of the baseline visit or    during the study treatment period;-   Currently taking anticoagulants or daily dose of aspirin greater    than 325 mg.-   Cough or flu remedies containing opiates or antihistamines within 2    weeks of the baseline visit or during the 6-week treatment period;    and-   Known allergy to any ingredients of the study drug or placebo.

Ninety-four subjects were randomized into one of six groups: 1 g E-EPAdaily (n=23), 2 g E-EPA daily (n=24), 4 g E-EPA daily (n=24), 1 gplacebo daily (n=7), 2 g placebo daily (n=8), and 4 g placebo daily(n=8). E-EPA was provided as 500 mg soft gel capsules containing >96%E-EPA and 0.2% dl-α-tocopherol as an antioxidant. Placebo capsulescontained 467 mg of liquid paraffin and 0.2% dl-α-tocopherol. Ninety-onesubjects completed the study. Two subjects in the 2 g E-EPA group andone subject in the 2 g placebo group discontinued the study.

The study consisted of a screening visit, a training visit, and fourstudy visits. At the screening visit, subjects' eligibility wasdetermined through cognitive tests (verbal paired associated learning[PAL] subscale, vocabulary subtest, Memory Assessment ClinicsQuestionnaire [MAC-Q], mini mental state evaluation [MMSE] and MINI[mini international neuropsychiatric interview; sections 1 and 2 ofDiagnostic and Statistical Manual of Mental Disorders, 4th Edition(DSM-IV) plus dysthymia]), haematology, clinical chemistry and 12-leadelectrocardiogram (ECG). At the training visit, subjects were shown howto use the CDR computerized system. Subjects took study drug for 6 weeksand on Days 0, 14, 28 and 42, subjects underwent the CDR cognitive testbattery.

At screening cognitive testing and suitability for the study wereassessed using the Verbal Paired Associates 1 (Wechsler Memory Scale),Vocabulary Subtest of the WAIS, MAC-Q, MMSE and MINI (DSM-IV Sections 1and 2 plus Dysthymia).

A selection of tasks from the CDR computerized cognitive assessmentsystem were administered at Visit 2 (training visit), Visit 3(baseline), Visit 4 (Day 14), Visit 5 (Day 28) and Visit 6 (Day 42).Parallel forms of the tests were presented at each testing session. Alltasks were computer-controlled, the information presented on highresolution monitors, and the responses recorded via a response modelcontaining two buttons: one marked ‘no’ and the other ‘yes’. Five CDRcomposite scores were used as the primary/secondary outcome variables.The task titles were:

-   Word Presentation-   Immediate Word Recall-   Picture Presentation-   Simple Reaction Time-   Digit Vigilance-   Choice Reaction Time-   Spatial Working Memory-   Numeric Working Memory-   Delayed Word Recall-   Word Recognition-   Picture Recognition-   Bond-Lader Visual Analogue Scales of Mood and Alertness-   Screen, Using the Computer Mouse

To ensure consistency of approach, full training on the cognitive testsand CDR test battery was provided to study site staff and studysubjects. The results of each variable were automatically recorded usingthe machine interface developed by CDR.

Blood samples (10 mL) were collected at Visit 1 (screening) and atVisits 4, 5 and 6. Analysis was performed by MSR Lipid Analysis,Scottish Crop Research Institute, Dundee, UK. The screening sample actedas baseline for the EFA measurements. Lipid was extracted from plasma,serum and RBC suspensions and converted into fatty acid methyl esterswhich were analyzed by gas chromatography to give fatty acid profiles asmicrograms fatty acid per gram of sample (μgFA/g) and normalized areapercent.

All randomized subjects with at least 1 visit post-baseline wereincluded in the Intent to Treat (“ITT”) population, regardless oftreatment actually received.

All randomized subjects that completed the study, excluding significantprotocol deviators, were defined as the Safety Per Protocol population.An Efficacy Per Protocol population was based on the Efficacycompleters. The intercept of the Safety and Efficacy Per Protocolpopulations defined the Study Per Protocol Population.

All randomized subjects that received at least 1 dose of studymedication were included in the Safety Population.

Summary statistics were provided for the ITT and Study Per ProtocolPopulations separately for all composite scores, major and supportivevariables. Summary statistics were performed for both the unadjusted anddifference from baseline data (i.e. the difference from the time matchedpredose assessments on Day 0). Summary statistics were calculated bytreatment, day and time-point. The summary statistics comprised n, mean,median, SD, standard error of mean (“SEM”), minimum and maximum values.

Difference from baseline data for each major variable was evaluated byan Analysis of Covariance (“ANCOVA”) using SAS® PROC MIXED Version 8.2.Fixed effects for treatment, day, time point, treatment by day,treatment by time point, treatment by day by time-point were fitted.Subject within treatment was fitted as a repeated effect using therepeated statement. The compound symmetry covariance structure was used.Subjects' time-matched predose assessments on Day 0 were used as acovariate in the analysis.

Least squares means (LS means) were calculated for treatment by day,treatment by time-point and treatment by day by time-point interaction.This formal analysis was conducted for the ITT and Study PP Populationsseparately.

Safety evaluations were based on the safety population. Safety andtolerability were assessed in terms of AEs, vital signs, 12-lead ECG,clinical laboratory data, medical history, and study drug compliance.Safety and tolerability data were presented by treatment group.

RBC and plasma EFA data were collected at baseline, Day 14, 28 and 42and summarized by visit for each treatment group. Change from baselineand percent change from baseline were also summarized. ANCOVA comparisonof ethyl-EPA dose groups and ethyl-EPA versus placebo was performed.

For Intent-to-Treat Self-Rated Contentment, there was a statisticallysignificant treatment by day interaction (p<0.001). The LS meandifference to placebo showed no statistically significant effects. ForStudy Per-Protocol Self-Rated Contentment, there was a statisticallysignificant treatment by day interaction (p<0.001). The LS meandifference to placebo showed no statistically significant effects.

For Intent-to-Treat Self-Rated Calmness, there was no statisticallysignificant effect of treatment, nor any treatment by day, treatment bytime-point or treatment by day by time-point interactions. For StudyPer-Protocol Self-Rated Calmness, there was no statistically significanteffect of treatment, nor any treatment by day, treatment by time-pointor treatment by day by time-point interactions. The LS mean differencesshowed a statistical trend for an increase in ratings versus placebo forethyl-EPA 4 g on Day 42 at PM 1 (p=0.071).

A post-hoc analysis compared the individual placebo groups (1 g, 2 g and4 g paraffin oil) with the corresponding ethyl-EPA doses.

The pattern of data provided evidence that ethyl-EPA 4 g might improvespeed in the attention based measures. For Power of Attention, there wasan overall benefit versus the corresponding placebo for 4 g on Day 42.The subtask Simple Reaction Time showed improvements in performance for4 g at PM 2 collapsed across days and at several time-points on Days 14and 42. The improvements for 4 g were most pronounced in the ChoiceReaction Time task, where there was an overall benefit versuscorresponding placebo for 4 g, reflecting a benefit for 4 g over placeboon all study days. The pattern of improvement in performance throughoutthe assessment days was quite convincing as the improvements began onDay 14 with improvements seen at 2 time points, whereas on Day 42ethyl-EPA 4 g was superior to placebo at every time point.

For Continuity of Attention, there were isolated declines orimprovements in performance, but there was no general pattern of effectsand it was considered unlikely these differences were due to the studycompound. For Quality of Working Memory and in the subtask measureNumeric Working Memory Sensitivity Index, there were, as in the originalanalyses, only isolated improvements and declines in performance thatwere most likely not treatment-related. However, for Spatial WorkingMemory Sensitivity Index, there was an overall benefit for ethyl-EPA 4 gover placebo on Day 42 in the Study PP Population, which corresponds tothe improvements seen for the attention based measures.

For Quality of Episodic Secondary Memory and contributing subtasks,there were a number of decreases for ethyl-EPA that could be explainedby the pre-existing differences in performance between the placebo andactive treatment groups which was seen in the original analyses. Incontrast to the original analysis, the subtask measures of Speed ofMemory showed some signs of improvement in performance for activetreatment, mostly for 1 g versus placebo. For Self-rated Alertness andSelf-rated Contentment, the 1 g dose showed decreases in ratings on Days14 and 28. However, these decreases were not correlated with a declinein performance in the CDR attention tasks. As with the original plannedanalysis, there were no differences between active treatment and placeboin Self-Rated Calmness.

Safety Results.

Subjects who used less than 80% of the prescribed dose were to beconsidered non-compliant; other than those subjects who withdrew forother reasons only 1 subject fell into this category and was withdrawn.

Overall, 139 treatment emergent AEs (“TEAEs”) were reported by 62(66.0%) of subjects during the study. Most TEAEs were considered mild inseverity and unrelated to study drug. More TEAEs were reported for theethyl-EPA treatment groups (105 events) compared to the placebotreatment groups (34 events). One SAE was reported for the ethyl EPA 2 gtreatment group and 3 subjects discontinued due to TEAEs: 2 subjectsfrom the ethyl-EPA 2 g treatment group (the primary reason fordiscontinuation for 1 of these subjects was non-compliance), and 1subject from the placebo 2 g treatment group.

There were no deaths during the study. No TEAEs were Definitely Relatedto the study drug. One subject receiving 1 g ethyl-EPA experiencednausea that was Probably Related to the study drug. Another subjectreceiving 4 g ethyl-EPA experienced diarrhea that was Probably Relatedto the study drug; another subject receiving 2 g placebo alsoexperienced diarrhea that was Probably Related to the study drug. Fivesubjects experienced nausea that was Possibly Related to the study drug;two were in the 1 g ethyl-EPA cohort; one was in the 2 g ethyl-EPAcohort; two were in the 4 g ethyl-EPA cohort. One subject receiving 2 gplacebo experienced headache that was Possibly Related to the studydrug. All other TEAEs were Not Related or Unlikely Related to the studydrug, and included nasopharyngitis (n=3), cystitis (n=2), cough (n=7),toothache (n=2), pharyngolaryngeal pain (n=2), back pain (n=2),pollakiuria (n=2), influenza-like illness (n=2), headache (n=15),diarrhea (n=2), and nausea (n=1).

One subject with a history of transient ischaemic attack, hypertensionand osteoarthritis of the hand and osteopaenia receiving 2 g ethyl-EPAexperienced worsening epigastric chest pain 17 days after the start ofthe study and 9 days after the last dose of the study drug. A plannedendoscopy revealed oesophagitis and a small hiatus hernia. The subjectwas treated with omeprazole, which settled her symptoms. The subject hadtaken felodipine, rosuvastatin, aspirin, glucosamine, and quinine within14 days of the onset of her symptoms. The study investigator determinedthat her symptoms were unrelated to the study drug and withdrew thesubject from the study. No other Serious Adverse Events occurred duringthe study.

Essential fatty acid parameters in plasma and RBCs was measured atbaseline and on Day 14, 28 and 48 (shown in Tables 1-6). Notable changesfor these parameters occurred in the ethyl-EPA treatment groups at Days14, 28 and 42 compared to placebo. EPA, DPAn-3 and EPA/AA ratio valuesincreased substantially from baseline, in plasma and RBC, to Day 42 forthe ethyl-EPA 1, 2 and 4 g treatment groups, but remained similar tobaseline in the placebo treatment groups. AA, DHA and DGLA valuesdecreased substantially from baseline, in plasma and RBC, to day 42 forthe ethyl EPA 1, 2 and 4 g treatment groups, but remained similar tobaseline in the placebo treatment groups. The difference in EPA, AA (RBConly), DPAn-3, DGLA (1 g only for plasma) and EPA/AA ratio levels in theplasma and RBC were significantly (LS means, p≤0.05) different for theethyl-EPA 4 g treatment group compared to the ethyl-EPA 1 g and 2 gtreatment groups.
